A question for Jonathan et al.: What is required of an operating system to port XeTeX to it successfully? A C compiler? C++? OS-level support for OpenType? Is porting freetype sufficient? A different library?
I'm asking mainly because of Plan 9, a UNIX-like OS with a C compiler (but no C++) to which the freetype library has been ported. There's an old port of TeX that doesn't work too well anymore, so there's been some talk about porting a modern TeX. (LuaTeX requires C++ for the PDF library it uses, so that's out for now.) --Joel
